I recently built a 4-element handheld yagi beam for 440. Its a really great design and has working really well. I get our 442.700 repeater really well and haven't had many chances to work it using simplex. Today, I had a south to north pass of the AO-51 satellite that went directly over my house. 90 degrees vertical over my house! I tuned the handheld to the receive frequency( I tried both frequencies and adjusted for dopplar as the bird made its pass) and I heard nothing the entire pass. Granted it was around 5:40 eastern time and maybe ppl were busy getting home from work, but I figured I would hear at least one person. I used the HRD satellite tracking program to adjust the elevation. Technically I did everything right, why didn't I hear anything? Any help will be greatly appreciated!
